Applying a Cluster Model to a Different Path

JKSJKS Member Posts: 1 Contributor I
Hello, 

I'm trying to use a cluster analysis to group regions within Texas that are not receiving cable spend with similar regions in Texas that are receiving cable spend to create a test & control experiment and then analyze web traffic among the regions with spend vs without to measure traffic lift. I used the multiply operator to create two paths (one for regions with $0 cable spend and another for regions with >$0 cable spend). I connected the k-means cluster to the path with $0 spend and am trying to apply that model to the regions with cable spend. I'm not sure if this is the best way to do this analysis but I'm having a difficult time applying the model to the regions with cable spend.

I pasted the XML code for reference. I'm fairly new to RapidMiner so I'm hoping someone can provide guidance on how to apply this model to the other path or if there's a better way to do this. 

I'm struggling
